OBJECTIVE
To find out whether taking images of the male and female genitals during coitus is feasible and to find out whether former and current ideas about the anatomy during sexual intercourse and during female sexual arousal are based on assumptions or on facts.
DESIGN
Observational study.
SETTING
University hospital in the Netherlands.
METHODS
Magnetic resonance imaging was used to study the female sexual response and the male and female genitals during coitus. Thirteen experiments were performed with eight couples and three single women.
RESULTS
The images obtained showed that during intercourse in the "missionary position" the penis has the shape of a boomerang and 1/3 of its length consists of the root of the penis. During female sexual arousal without intercourse the uterus was raised and the anterior vaginal wall lengthened. The size of the uterus did not increase during sexual arousal.
CONCLUSION
Taking magnetic resonance images of the male and female genitals during coitus is feasible and contributes to understanding of anatomy.
目的
探究在性交过程中拍摄男性和女性生殖器图像是否可行，以及了解过去和当前关于性交过程及女性性唤起期间的解剖学观点是基于假设还是事实。
设计
观察性研究。
地点
荷兰的大学医院。
方法
使用磁共振成像来研究女性的性反应以及性交过程中的男性和女性生殖器。对八对夫妇和三名单身女性进行了13次实验。
结果
获得的图像显示，在“传教士体位”性交时，阴茎呈飞镖形状，其长度的1/3由阴茎根部组成。在无性交的女性性唤起期间，子宫上抬，阴道前壁延长。性唤起期间子宫大小未增加。
结论
在性交过程中拍摄男性和女性生殖器的磁共振图像是可行的，有助于对解剖学的理解。
